__________ prevents IP calls from being extended across a WAN link, if the additional WAN bandwidth required would exceed the QoS-allocated bandwidth for concurrent calls.

In most cases, dropping the call is not desirable. What is implemented to reroute the call across the PSTN?

7.

1 point

Which of the following are peer-to-peer gateway protocols?

8.

1 point

CAC prevents what from happening when in conjunction with QoS and LLQ, and what can be used to help prevent this from happening?

Prevents excess calls from degrading call quality by dropping them. AAR will kick in and reroute calls over the PSTN.

Since location-based CAC does not work in a distributed deployment, LLQ

LLQ prevents CAC from taking too much bandwidth. DNIS can be used to reroute excess calls.

During WAN failure CAC will re-register with SRST. CFUR will prevent un-registration from happening thus preventing disruption of service.

What is a Translation Pattern?

A specific pattern of digits that, when matches, triggers a customizable call-coverage system.

Matches a string of dialed digits and transforms them to a new dialed string, which is in turn resubmitted to digit analysis and routed to a different target.

Matches a set of dialed digits and triggers a call-routing process that can include one or more potential paths, providing a hierarchical set of call-routing options

A pattern or range of patterns that CUCM can use to temporarily hold a call until a user dials the call park number to pick it up from any IP phone.

What is the relationship between a Route Group and Route List?

A Route List is an ordered list of Route Groups.
